It is time to share the data that I have collected and stored for over 10 years now. You can find a lot of documentation, addons, source files and releases.
Happy downloading! :)
In regards to people demands for a launcher with updates, I am sharing the free version of the p4f launcher. The launcher can be used in fact for any game. It was released in 2013 but most if not all downloading links were lost or expired.
Title: Launcher System
Latest version: 0.9.1...
